是否有可能从HTML5音频元素的Icecast获取元数据？ [英] Is it possible to get Icecast metadata from HTML5 audio element?

问题描述

我使用的音频元素流从icecast服务的OGG来源。是否音频元素抽取冰冷的元数据，并有通过JavaScript访问它的方式？

I am using audio element to stream an ogg source from an icecast server. Does the audio element extract icy metadata and is there a way to access it through javascript?

基本上，我想显示正在播放一个广播电台，我流的信息。我有哪些选择？

Basically, I want to show "currently playing" information of a radio station I am streaming. What are my options?

谢谢！

推荐答案

没有，你的HTML5元素只知道流数据，并且甚至没有做出适当的请求来获取元数据。

No, your HTML5 elements are only aware of the stream data, and aren't even making the appropriate request to fetch the metadata.

现在，这个以任何方式是不可能的。你只需做服务器端。 （见特别是第二个链接。）

Now, this isn't impossible by any means. You just have to do it server-side. (See that second link in particular.)

我还要指出的是，一个完全成熟的SHOUTcast服务器上（未与icecast理解，但它值得一试测试）生成7.html，它包含了监听器，监听器的最大峰值听众人数的数据，立体声/单声道，比特率和当前曲目的名称作为逗号分隔值。像这样的：

I should also point out that on a full-blown SHOUTcast Server (haven't tested with Icecast, but its worth a try) generates "7.html" which contains data on the number of listeners, max listeners, peak listeners, stereo/mono, bitrate, and current track name as comma-separated values. Like this:

2,1,33,625,2,128，J Mascis - 没有足够

如果你可以获取的http：// yourstreamingserver：端口/ 7.html ，那么你就可以得到这个数据很容易

If you can fetch http://yourstreamingserver:port/7.html, then you can get this data very easily.
